According to MDM:

' The tagName read-only property of the Element interface returns the tag name of the element on which it's called. For example, if the element is an <img>, its tagName property is "IMG" '

I hope it helps.

But why is that? Why must it be capitalised? I understand that that is what you do, but what is the reasoning for it?
